From 66597eb633359cb6e2d9d905a3fe29de74b8ee1a Mon Sep 17 00:00:00 2001 From: r33drichards Date: Wed, 3 Jun 2026 19:11:19 -0700 Subject: [PATCH 1/7] feat(linux): emit AT-SPI + Set-of-Marks annotated screenshots for skeleton matrix For each read-only skeleton app in the background-GUI NixOS test matrix, emit two annotated screenshots as CI artifacts: `-atspi.png` (AT-SPI element boxes + screen coords) and `-som.png` (cua Set-of-Marks). chromium/tk full entries are out of scope. Driver (platform-linux): - Add additive `elements` array to `get_window_state`'s structured JSON output: `{element_index, role, name, x, y, width, height}` in screen coordinates. - New `atspi::get_all_element_bounds(pid)` walks the tree once and queries each action node's `Component.GetExtents(Screen)`, best-effort (per-node failures are skipped, never error the call). Avoids the O(n^2) reconnect of calling the existing per-node `get_element_bounds`. In-VM test (linux-background-gui.nix): - skeletonMcpTest now calls `get_window_state` after the read-only get_text loop, parses `structuredContent.elements`, and writes /tmp/cua-elements.json. - skeletonDrive captures a full-screen still (`import -window root`, screen coords align 1:1 with AT-SPI bounds), draws a stdlib-python + ImageMagick overlay (red box + label per element), and copies both raw + atspi PNGs into $out before any assertion. All read-only assertions are unchanged. Workflow (nix-build.yml): - Widen the per-job artifact glob to include PNGs and upload `artifacts/*`. - New `som-annotate` aggregate job (needs nix-checks, if: always(), off the hot path): downloads all artifacts, installs cua-som, runs OmniParser on each raw `.png` to emit `-som.png`, uploads `cua-driver-linux-som-overlays`. - Mention the new artifact in the visual-artifacts PR comment. Validation (macOS host; VM tests + SoM run only in CI): - cargo check -p platform-linux --target x86_64-unknown-linux-gnu: clean. - nix-instantiate --parse of the test file: ok. - YAML safe_load of the workflow: ok. - nix eval of a skeleton check drvPath: produces a valid .drv.
